Crop moisture deficiency diagnosis method based on mobile equipment

Abstract

The invention discloses a crop moisture deficiency diagnosis method based on mobile equipment. The method comprises that 1) auxiliary devices, namely field air thermometers and a ground full-evaporation reference plane, are arranged in the field; 2) a special-purposed infrared camera is installed on the mobile equipment; 3) the infrared camera is used to shoot a field which needs diagnosis, and the number of the air thermometer in the area is recorded; 4) the infrared camera is used to shoot the ground full-evaporation reference plane near a target area; 5) the temperature read from the thermometer is input to a special-purposed APP of the mobile equipment, and infrared images of the target area and the ground full-evaporation reference plane are introduced; and 6) according to the input data and introduced images, the APP carries out operation automatically to obtain a moisture deficiency distribution map in the shot target area, and highlight display and early warning are carried out on the area whose crop moisture deficiency index is higher than a critical value. The method is suitable for monitoring the crop moisture states of farmlands of intermediate and small areas, is characterized by being portable and rapid, accurate and reliable in diagnosis, and is conducive to realizing accurate irrigation of agriculture and improving the modern level of agriculture.

Description

technical field [0001] The invention relates to the technical field of agricultural irrigation, in particular to a method for diagnosing crop water deficit based on a mobile device. Background technique [0002] Infrared thermal imaging technology is a new type of machine vision technology. This technology studies the principles and laws of infrared radiation emission, transmission and reception. By converting and processing the received infrared information, the details of the image are obtained by using the difference in the radiation of each part of the scene itself. Thermal imaging technology can observe the changes of things from another angle by imaging things. The technology was previously used in military and industrial applications. With the development of thermal imaging technology and the improvement of precision, and infrared thermal imaging technology has the advantages of being less affected by the environment and can accurately reflect the regional temperatu...

Problems solved by technology

At present, the water deficit diagnosis technology based on infrared images of crop canopies mainly takes infrared images with infrared cameras on platforms such as handheld or unmanned aerial vehicles, and then imports special software on the computer to process the appeal graphics to obtain the shooting area. The state of water deficit. It takes a period of time for this type of method to draw a conclusion from the image taken. It is difficult to obtain the state of crop water deficit in real time at the shooting site.
